Demetae

The Demetae was a Briton tribe from Moridunon in Wales, originally from Devezes in southern France. They were an Iron Age civilization that inhabited southern Wales along with the Silurii, and were fierce enemies of the Iceni tribe. From 272 BC to 270 BC, they fought the Iceni, but were conquered when Moridunon fell.

History
The Demetae tribe settled in southern Wales with their capital at the settlement at Moridunon, while their roots were planted in the southern French department of Devezes in the Pyrenees. An Iron Age civilization, they were known to be fierce warriors who were neighbors to the Silurii and Iceni. They fought with the Iceni on many occasions, as they were in the way of peace with their devious leader Flatucius.

In 271 BC, the Iceni poisoned the wells of Moridunon as the first step to conquering their Demetae rivals. Dagomaros, the Iceni elder, led an army into the land of the Demetae tribe and laid siege to Moridunon, held by elders Maros, Ollilos, and Imbetos. The city fell to the Iceni after a gory battle, and the Demetae tribe was conquered.

In 60 AD, the Demetae would assist the Iceni, Trinovantes, and other Britons in rebelling against the Roman Empire during the Revolt of the Iceni, but were crushed again.
